## Gradio UI
Coming soon again :)
We can launch the a user-interface version with:
```commandline
python latentblending/gradio_ui.py
```
With the UI, you can iteratively generate your desired keyframes, and then render the movie with latent blending it at the end.
## Example 1: Simple transition
![](example1.jpg)
To run a simple transition between two prompts, see `examples/single_trans.py`
To run a simple transition between two prompts, see `examples/single_trans.py`, or [check this volcano eruption ](https://youtu.be/O_2fpWHdnm4).
## Example 2: Multi transition
To run multiple transition between K prompts, resulting in a stitched video, see `examples/multi_trans.py`.

# Parameters
## Main
- waiting time: set your waiting time for the transition. high values = better quality
- video duration: seconds per segment
- height/width: in pixels
## Diffusion settings
- num_inference_steps: number of diffusion steps
- guidance_scale: latent blending seems to prefer lower values here
- negative prompt: enter negative prompt here, applied for all images
## Last image crossfeeding
- branch1_crossfeed_power: Controls the level of cross-feeding between the first and last image branch. For preserving structures.
- branch1_crossfeed_range: Sets the duration of active crossfeed during development. High values enforce strong structural similarity.
- branch1_crossfeed_decay: Sets decay for branch1_crossfeed_power. Lower values make the decay stronger across the range.
## Transition settings
- parental_crossfeed_power: Similar to branch1_crossfeed_power, however applied for the images withinin the transition.
- parental_crossfeed_range: Similar to branch1_crossfeed_range, however applied for the images withinin the transition.
- parental_crossfeed_power_decay: Similar to branch1_crossfeed_decay, however applied for the images withinin the transition.
- depth_strength: Determines when the blending process will begin in terms of diffusion steps. Low values more inventive but can cause motion.
- guidance_scale_mid_damper: Decreases the guidance scale in the middle of a transition.
